Archived Data Table Description

The following describes the information contained within the columns of the Archived Data Table. The table can be downloaded from the Data>Archived Data tab.

Below is a representation of what the spreadsheet looks like.

The description of the columns is as follows:

DATE: YYYY/MM/DD
TIME: The local time when the row was written to the file. The data for this entry is for the time period since the last entry.

VOL(NS): Total vehicle count for near-side
VOL(FS): Total vehicle count for far-side

SPEED(NS): Average speed for near-side
SPEED(FS): Average speed for far-side

CR(NS): Total number of cars near-side
TK(NS): Total number of trucks near-side
TR(NS): Total number of tractor-trailers near-side
MC(NS): Total number of motorcycles near-side
UN(NS): Total number of unclassified vehicles near-side

CR(FS): Total number of cars far-side
TK(FS): Total number of trucks far-side
TR(FS): Total number of tractor-trailers far-side
MC(FS): Total number of motorcycles far-side
UN(FS): Total number of unclassified vehicles far-side

CAMERA_MOVED: “no” or “moved”
Indicated whether the software detected camera motion during this data collection period

CALIB_PRESET: {near}
The preset that the software used during this data collection period. If the number is prefixed with “near”, that indicates that the drift correction was applied. A value of 0 (with or without “near”) indicates that the software could not match any configured preset.

#LANES(NS): Number of lanes on the near-side
#LANES(FS): Number of lanes on the far-side
The subsequent set of columns are for each lane, with lane numbers starting with 1 and increasing with distance from the camera.

VOL(1: NS-1): Vehicle count for lane 1 with label “NS-1”
SPEED(1: NS-1): Average speed of vehicles in this lane.
DENSITY(1: NS-1): Estimated vehicles/mile (or vehicles/km)
DET_OCC(1: NS-1): Estimated occupancy (% of time a simulated detector in that lane would be ON)
CR(1: NS-1): Number of cars in this lane
TK(1: NS-1): Number of trucks in this lane
TR(1: NS-1): Number of tractor-trailers in this lane
MC(1: NS-1): Number of motorcycles in this lane
UN(1: NS-1): Number of unclassified vehicles in this lane
